Maybe someone who's had both on can give a better answer. But from what I understand, Berk is more "what the car should have sounded like from the factory". Pretty quiet at idle, has a nice roar in the lower rpms and harmonizes with the VQ at WOT.

F.I. is a bit more exotic and has a deeper tone at the lower rpms. With stock cats, it's definitely louder from what I've read and heard.
